Background 

On March 18, 2020, an Airbus Model 

A321–231 airplane, powered by 

International Aero Engines AG (IAE AG) 

Model V2533–A5 engines, experienced 

an uncontained HPT 1st-stage disk 

failure that resulted in high-energy 

debris penetrating the engine cowling. 

Based on a preliminary analysis of this 

event, on March 21, 2020, the FAA 

issued Emergency AD 2020–07–51 

(followed by publication in the Federal 

Register on April 13, 2020, as a final 


lotter on DSK11XQN23PROD with RULES1
57000 Federal Register / Vol. 88, No. 161 / Tuesday, August 22, 2023 / Rules and Regulations 

rule, request for comments (85 FR 

20402)), which requires the removal 

from service of certain HPT 1st-stage 

disks installed on IAE AG Model 

V2522–A5, V2524–A5, V2525–D5, 

V2527–A5, V2527E–A5, V2527M–A5, 

V2528–D5, V2530–A5, and V2533–A5 

engines. A manufacturer investigation 

found that the failure of the HPT 1ststage disk was a result of a material 

anomaly attributed to deficiencies in the 

manufacturing process. 

Based on the analysis performed since 

that March 2020 event, the 

manufacturer, PW, identified a different 

population of HPT 1st-stage disks and 

HPT 2nd-stage disks that are subject to 

the same unsafe condition identified in 

AD 2020–07–51. In response, the FAA 

issued AD 2021–19–10, Amendment 

39–21728 (86 FR 50610, September 10, 

2021) (AD 2021–19–10), which requires 

the removal from service of certain HPT 

1st-stage disks and HPT 2nd-stage disks 

installed on IAE LLC Model PW1122G– 

JM, PW1124G1–JM, PW1124G–JM, 

PW1127G1–JM, PW1127GA–JM, 

PW1127G–JM, PW1129G–JM, 

PW1130G–JM, PW1133GA–JM, and 

PW1133G–JM engines. 

Since the FAA issued AD 2021–19– 

10, PW identified another 

subpopulation of HPT 1st-stage disks 

and HPT 2nd-stage disks that, because 

of their susceptibility to the same 

material anomaly, require inspection 

and possible removal from service. In 

response, the FAA issued AD 2022–19– 

15, Amendment 39–22184 (87 FR 

59660, October 3, 2022; corrected 87 FR 

64156, October 24, 2022) (AD 2022–19– 

15), which requires performing a USI of 

the HPT 1st-stage disk and HPT 2ndstage disk and, depending on the results 

of the inspections, replacement of the 

HPT 1st-stage disk or HPT 2nd-stage 

disk installed on IAE LLC Model 

PW1122G–JM, PW1124G1–JM, 

PW1124G–JM, PW1127G1–JM, 

PW1127GA–JM, PW1127G–JM, 

PW1129G–JM, PW1130G–JM, 

PW1133GA–JM, and PW1133G–JM 

engines. 

Since the FAA issued AD 2022–19– 

15, on December 24, 2022 an Airbus 

Model A320neo airplane powered by 

IAE LLC Model PW1127GA–JM engines, 

experienced an HPC IBR–7 failure that 

resulted in engine shutdown and 

aborted take-off. Following this event, 

the manufacturer conducted a records 

review of production and field-returned 

parts, and re-evaluated their engineering 

analysis methodology. The new analysis 

identified HPT 1st-stage hubs and HPT 

2nd-stage hubs that are susceptible to 

failure much earlier than previously 

determined. On August 4, 2023, PW 

issued service information to instructing 

operators to conduct a USI to detect 

cracks and prevent premature failure. 

The new service information 

necessitates action much earlier than 

the timing mandated in AD 2022–19–15. 

The manufacturer’s updated analysis 

also identified PW1400G series engines 

that contain HPT 1st-stage hubs and 

HPT 2nd-stage hubs that are also subject 

to this vulnerability and therefore need 

immediate inspection. This condition, if 

not addressed, could result in 

uncontained disk failure, release of 

high-energy debris, damage to the 

engine, damage to the airplane, and loss 

of the airplane. The FAA is issuing this 

AD to address the unsafe condition on 

these products. 

FAA’s Determination 

The FAA is issuing this AD because 

the agency has determined the unsafe 

condition described previously is likely 

to exist or develop in other products of 

the same type design. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed PW Special 

Instruction No. 149F–23, dated August 

4, 2023. This service information 

provides the list of affected HPT 1ststage hubs and HPT 2nd-stage hubs, 

identified by part number and serial 

number, installed on certain IAE LLC 

engines. 

Pratt & Whitney Service Bulletin 

PW1000G–C–72–00–0188–00A–930A– 

D, Issue No: 002, dated July 8, 2022, was 

previously approved for incorporation 

by reference on November 7, 2022 (87 

FR 59660, October 3, 2022; corrected 87 

FR 64156, October 24, 2022). 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in ADDRESSES. 

AD Requirements 

This AD requires performing a USI of 

the HPT 1st-stage hub and HPT 2ndstage hub and, depending on the results 

of the inspections, replacement of the 

HPT 1st-stage hub or HPT 2nd-stage 

hub. 

Differences Between the AD and the 

Service Information 

PW Service Bulletin PW1000G–C–72– 

00–0188–00A–930A–D, Issue No: 002, 

dated July 8, 2022, includes only 

PW1100G–JM series engines in its 

applicability. This AD applies to both 

PW1100G–JM series engines and 

PW1400G–JM series engines. 

Interim Action 

The FAA considers this AD to be an 

interim action. This unsafe condition is 

still under investigation by the 

manufacturer and, depending on the 

results of that investigation, the FAA 

may consider further rulemaking action. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause,’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies forgoing notice 

and comment prior to adoption of this 

rule. The presence of material anomalies 

in the HPT 1st-stage hubs and HPT 2ndstage hubs discovered after the 

December 24, 2022 engine shutdown 

and aborted take-off could lead to 

premature fracture and uncontained 

failure, which indicates an immediate 

safety of flight problem. The 

manufacturer also recently conducted a 

records review of production and fieldreturned parts, and re-evaluated their 

engineering analysis methodology and 

identified HPT 1st-stage hubs and HPT 

2nd-stage hubs that require USI much 

earlier than previously required. The 

manufacturer issued service information 

on August 4, 2023 instructing operators 

to remove these engines from service by 

September 15, 2023 due to the urgency 

of the safety of flight issue. The longer 

these parts remain in service, without 

the inspections required by this AD, the 

higher the probability of failure. 

Therefore, the compliance time for these 

required inspections is shorter than the 

time necessary for the public to 

comment and for publication of the final 

rule. Accordingly, notice and 

opportunity for prior public comment 

are impracticable and contrary to the 

public interest pursuant to 5 U.S.C. 

553(b)(3)(B). 

In addition, the FAA finds that good 

cause exists pursuant to 5 U.S.C. 553(d) 

for making this amendment effective in 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 88, No. 161 / Tuesday, August 22, 2023 / Rules and Regulations 57001 

less than 30 days, for the same reasons 

the FAA found good cause to forgo 

notice and comment. 

Regulatory Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because FAA 

has determined that it has good cause to 

adopt this rule without prior notice and 

comment, RFA analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 20 engines installed on airplanes 

of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

USI the HPT 1st-stage hub ........................................... 100 work-hours × $85 per hour = 

$8,500.

$0 $8,500 $170,000 

USI the HPT 2nd-stage hub .......................................... 100 work-hours × $85 per hour = 

$8,500.

0 8,500 170,000 

The FAA estimates the following 

costs to do any necessary replacement 

that would be required based on the 

results of the inspection. The agency has 

no way of determining the number of 

aircraft that might need this 

replacement: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replace HPT 1st-stage hub or HPT 2nd-stage hub ..................... 1 work-hours × $85 per hour = $85 ............ $171,000 $171,085 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs describes in more 

detail the scope of the Agency’s 

authority. 

The FAA is issuing this rulemaking 

under the authority described in 

Subtitle VII, Part A, Subpart III, Section 

44701: General requirements. Under 

that section, Congress charges the FAA 

with promoting safe flight of civil 

aircraft in air commerce by prescribing 

regulations for practices, methods, and 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will not have a 

substantial direct effect on the States, on 

the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

under the destination of China, one 

under the destination of Indonesia, two

SUPPLEMENTARY INFORMATION: 

Background 

Unverified List Changes 

The UVL, found in supplement no. 6 

to part 744 of the EAR (15 CFR parts 

730–774), contains the names and 

addresses of foreign persons who are or 

have been parties to a transaction, as 

described in § 748.5 of the EAR, 

involving the export, reexport, or 

transfer (in-country) of items subject to 

the EAR. These foreign persons are 

added to the UVL because BIS or federal 

officials acting on BIS’s behalf were 

unable to verify their bona fides (i.e., 

legitimacy and reliability relating to the 

end use and end user of items subject 

to the EAR) through the completion of 

an end-use check. Sometimes these 

checks, such as a pre-license check 

(PLC) or a post-shipment verification 

(PSV), cannot be completed 

satisfactorily for reasons outside the 

U.S. Government’s control. 

There are any number of reasons why 

these checks cannot be completed to the 

satisfaction of the U.S. Government. The 

reasons include, but are not limited to: 

(1) reasons unrelated to the cooperation 

of the foreign party subject to the enduse check (for example, BIS sometimes 

initiates end-use checks but is unable to 

complete them because the foreign party 

cannot be found at the address indicated 

on the associated export documents and 

BIS cannot contact the party by 

telephone or email); (2) reasons related 

to a lack of cooperation by the host 

government that fails to schedule and 

facilitate the completion of an end-use 

check, for example by host government 

agencies’ lack of responses to requests to 

conduct end-use checks, actions 

preventing the scheduling of such 

checks, or refusals to schedule checks in 

a timely manner; or (3) when, during the
